Thomas Jefferson served as president from 1801 to 1809. His time in office included significant changes in domestic and foreign policy, important land acquisitions, and interactions with Native Americans.
Jefferson kept Alexander Hamilton’s national bank and followed previous debt management plans. He focused on avoiding European conflicts to keep the U.S. neutral. He eliminated excise taxes, including the whiskey tax, showcasing fiscal responsibility and lowering national debt. Additionally, he repealed the Alien and Sedition Acts, which had limited immigration and suppressed free speech.
A major achievement during Jefferson's presidency was the Louisiana Purchase in 1803, which doubled the size of the United States. This acquisition included land stretching from the Mississippi and Missouri Rivers to New Orleans, which was vital for trade. Concerns arose when Spain revoked the tax-free status for the Port of New Orleans. Jefferson sent diplomats to offer $10 million for New Orleans, but Napoleon offered the entire territory for $15 million, which the U.S. accepted. Though this went against Jefferson’s strict interpretation of the Constitution, he submitted the deal, and the Senate approved it.
The Louisiana Purchase removed France from North America and strengthened U.S. security. The Lewis & Clark Expedition (1804-1806) explored this new land, mapping it and engaging with Native American tribes, which also helped assert U.S. claims to the Oregon Territory.
Jefferson faced challenges regarding judicial appointments from the previous administration. He told Secretary of State James Madison not to deliver certain commissions, leading to the Supreme Court case Marbury v. Madison. The Court ruled that although Marbury was entitled to his commission, the Judiciary Act of 1789 was unconstitutional, establishing the principle of judicial review.
In the 1804 election, Jefferson overcame Federalist opposition and secured his position, reinforcing his policies.
Jefferson's presidency also had conflicts with Barbary pirates. Previous governments had paid tribute to avoid ship seizures, but Jefferson sent naval forces to protect American ships instead, resulting in conflicts by 1805.
During Jefferson's term, tensions grew with Britain and France due to their ongoing war, with both nations seizing U.S. merchant ships. Impressment of American sailors was a major issue, leading to events like the Chesapeake-Leopard Affair, which caused public outrage. Jefferson preferred diplomatic and economic solutions rather than military action.
Jefferson aimed to economically pressure Britain and France, leading to the Trade Prohibition Act, which limited U.S. trade worldwide. This caused economic downturns, especially in northern states, and while the act was repealed in 1809, trading restrictions continued.
